What are IIFEs in JavaScript?

Can you explain what IIFEs are in JavaScript?

Sure! IIFEs, or Immediately Invoked Function Expressions, are functions that run as soon as they are defined.

Why would I use an IIFE instead of a regular function?

IIFEs help create a private scope, preventing variables from polluting the global scope and avoiding naming conflicts.

Can you show me an example of an IIFE?

Of course! Here's a simple example: (function() { console.log('Hello, IIFE!'); })(); This will log 'Hello, IIFE!' immediately.

Are there any downsides to using IIFEs?

One downside is that they can make debugging harder since the variables inside are not accessible from the outside.
